This is done by connecting a device called a modem to the digital computer. This process of converting a digital signal to an analog signal is known as modulation. On the receiving end, the incoming analog signal is converted back to digital form in a process known as demodulation.

Erie Company manufactures a mobile fitness device called the Jogging Mate. The company uses standards to control its costs. The

Tom [10]

a. Standard labor-hours is 7920 hours.

b. Standard labor cost allowed is $42,768.

c. The labor spending variance is $1588(U).

d. The labor rate variance is $1706 and the labor efficiency variance $3294(U).

e. The variable overhead rate is $5971(U) and efficiency variances for the month $5580(U).

<u>Explanation:</u>

a)Standars hours(SH) allowed to make 19800 jogging mates

=SH per unit $\times$ 19800

=(24/60)*19800

=7920 hours

24/60 has been taken to convert minutes into hours.

b)Standard Labor Cost (SC) of 19800 jogging mates

$=19800 \times SC per unit=19800 \times $2.16\\=$42,768$

=$42,768

c)Labour Spending Variance

$=Standard Cost - Actual Cost(AC)=$42,768 - $44,356=$1588(U)$

=$1588(U)

d)Labor Rate Variance

$=(SR per hour-AR per hour)\timesAH=(5.4-5.2)*8530=$1706(F)$

=$1706

Actual Hours(AH) * Actual Rate per hour(AR)= Actual Cost(AC)

$8530 \times AR = $44,356$

$AR = \frac{44356}{8530}\\ \\AR = 5.2$

Labor Efficiency Variance

$=(SH-AH) \times SR\\=(7920-8530)*$5.4=$3294(U)$

=$3294(U)

e) Variable overhead rate variance = Actual hours worked (Standard overhead rate - Actual overhead rate)

= 8530 (4.5 - 5.20)

= $5971(U)

Actual overhead rate = $44,356 / 8530 = 5.20

Variable overhead efficiency variance = Standard overhead rate (Standard hours - Actual hours)

= 4.50 (7290 - 8530)

= $5580(U).

Answer: d. The car is a normal goods for Jim

Explanation: if an individual's income goes up by a certain percentage or amount and, in response, the quantity demanded of good rises by rises in response to the income increase, such good can be considered a normal good. It is also defined as such good for which the income elasticity of demand is positive but less than one. This is the same scenario that has happened with Jim. His demand for better automobile increased as a result of an increase in his income.
